Abstract
The invention relates to a process for the production of a multilayer finish by applying a base coat comprising an aqueous (water-borne) coating composition to a substrate and then applying a layer of a clear coat containing organic solvents, which gives coatings having excellent hardness and gloss. To this end, the base coat layer is produced by applying an aqueous coating composition, containing, in addition to water, one or more pigments and optionally one or more organic solvents, neutralisers and additives which are conventional in paints, as binder: a combination of I) from 99.5 to 85 % by weight of one or more aqueous, physically drying polyurethane binders having such a content of OH groups and acid functions that the OH number does not exceed 10 and the acid number does not exceed 30, of which from 10 to 50 % by weight based on the solids content of component I), can be replaced by one or more unsaturated products of the reaction of carboxyl-functional polycondensates with ethylenically unsaturated monomers, and II) from 0.5 to 15 % by weight of one or more polyisocyanates which are liquid at room temperature or have been liquefied by means of organic solvents and contain more than one free isocyanate group, from the group consisting of diisocyanates of the formula <IMAGE> in which the radicals R1 and R2 can in each case be identical or different and where R1 = -H or -CnH2n+1 R2 = -CnH2n+1, where n = an integer from 1 to 6 and A = a single bond, an aromatic or alicyclic radical or a linear or branched aliphatic radical having 1 to 12 carbon atoms, and/or polyisocyanates derived therefrom, where up to 40 % by weight, based on the solids content of the polyisocyanate component II, can be replaced by one or more different polyisocyanates which are liquid at room temperature or have been liquefied by means of organic solvents and contain more than one free isocyanate group, where the percentages by weight of the components I) and II) are in each case based on their solids content and add up to 100 % by weight, and where component II) is added to the coating composition just before its application.
